Stabilization of Fine-Grained Soil for Road and Airfield Construction
A laboratory study was conducted to determine the feasibility of stabilizing an organic silt for use in sub-base or base courses for all-weather, low-volume roads and airfields in Alaska. The soil used in this study has an organic content of 12% and a modified Proctor value of 79.1 lb/cubic foot at a 29% moisture content. The stabilizers evaluated were: cement, cement with additives (calcium chloride, hydrogen peroxide, sodium sulfate, and lime), lime, lime/fly ash, asphalt emulsion, tetrasodium polyphosphate, and calcium acrylate. Unconfined compressive strengths obtained were: 39 lb/square inch with 20% cement, 64 lb/square inch with 20% cement and 2% calcium chloride, 51 lb/square inch with asphalt emulsion, and 348 lb/square inch with calcium chloride. Lime and lime/fly ash proved to be ineffective for this soil. Although tetrasodium polyphosphate did not improve the soil's strength it did reduce frost susceptibility and permeability. Keywords: Chemical stabilizers, Organic soils, Soil stabilization.
